Inter-reviewer conflict resolution

ABSTRACT

One embodiment provides a method, including: receiving a plurality of review comments from each of a plurality of reviewers tasked with reviewing a document; categorizing each of the plurality of review comments into one of a plurality of review topics; identifying a conflict between a first review comment provided by one of the plurality of reviewers and a second review comment provided by another of the plurality of reviewers, wherein the identifying a conflict comprises (i) identifying a sentiment of the first review comment and a sentiment of the second review comment and (ii) determining that the sentiment of the first review comment and the sentiment of the second review comment are different; and generating a question set comprising a plurality of questions based upon a conflict identified for a review comment of the corresponding reviewer, wherein the corresponding reviewer answering the generated question resolves the conflict.

BACKGROUND

When documents (e.g., technical papers, grant proposals, manuscripts, presentations, etc.) are prepared by one or a group of people, they are generally reviewed by one or more reviewers. Sometimes each of the reviewers is responsible for reviewing a certain feature or aspect of the document. For example, one or a group of reviewers may be responsible for reviewing the document for technical accuracy, whereas another reviewer or group of reviewers is responsible for reviewing the document for novelty. Alternatively, all of the reviewers may be responsible for reviewing all aspects or features of the document.

Each reviewer may have a different style of reviewing and/or may expect different features or aspects to be presented in a particular manner. For example, one reviewer may provide detailed comments or questions on aspects of the document, whereas another reviewer may provide short comments without much substance. As another example, one reviewer may expect all related documents or works to be cited within a document, whereas another reviewer may only expect the most closely related documents or works to be cited within a document. As another example, one reviewer may provide more subjective comments, whereas another reviewer may provide more objective comments.

Since different reviewers provide comments to documents differently, it can be difficult for the person or group of people receiving the comments to determine what changes need to be made in order to resolve the comments. For example, a reviewer may indicate that the document does not include novel features, but does not indicate what novel features are missing or why the reviewer thinks that the novel features are missing. In other words, the reviewer may provide an overall general comment without any supporting details explaining the reasoning behind the comment. Additionally, a reviewer could provide comments that conflict with comments provided by other reviewers. For example, one reviewer may indicate that the document accurately captures the technical details, and another reviewer may indicate that the document fails to capture all the technical details.

To resolve these inter-reviewer conflicts conventionally requires back-and-forth between the reviewers and/or the document drafter. This process can be very time consuming and requires a significant effort from all parties. For example, it may be difficult to get all parties together to communicate in a single session, so the communications must occur through another medium that requires multiple hours or days to resolve. Additionally, if the reviewers have to communicate through a textual medium, it may take many communications to fully convey or understand a point being made by the reviewer. Thus, the conventional technique for resolving comments is very time consuming, labor intensive, and inefficient.

Accordingly, the techniques and systems as described herein provide a system and technique for resolving inter-reviewer conflicts by generating a minimal question set for each of the reviewers that, upon receiving responses to the question set, will resolve the conflicts. The system receives a plurality of comments from each of a plurality of reviewers that are tasked with reviewing a document. The system can then categorize the comments into one of a plurality of review topics, for example, novelty, technical details, relevance, or the like. The system may further categorize the comments into finer-grained topics, for example, novelty 1, novelty 2, or the like.

The system can then identify conflicts between comments provided by different reviewers that are categorized into the same topic. For example, the system may analyze the sentiment of each of the comments to determine whether the comment has a positive, negative, or neutral sentiment. If the sentiments of two or more comments are different across reviewers, the system may determine that there is a conflict between the review comments provided by the reviewers. Identification of a conflict may also include identifying comments provided by reviewers that are lacking in substance. In other words, a conflict may be identified if a comment is a subjective comment without any supporting reasoning for the provided comment. From the identified conflicts and subjective comments, the system can automatically generate a minimal question set for each of the reviewers. These question sets are generated in a manner such that an answer to the question set resolves the conflicts between the reviewers. In other words, the system automatically generates the least number of questions for each of the reviewers that results in resolution of the conflicts once the reviewer has provided a response to each of the questions in the question set.

Such a system provides a technical improvement over current systems for document review by providing a technique that can automatically generate a minimal question set for each reviewer, where reviewer responses to the question set will resolve any conflicts between reviewer comments. The system categorizes comments made by reviewers and can identify conflicts between comments made by different reviewers. Based upon these conflicts, which also include comments that need additional detail, the system can automatically generate natural language questions to be presented to each reviewer that are designed to resolve the conflicts. Thus, instead of the conventional system which is time consuming, labor extensive, and inefficient, the described system provides an efficient technique for resolution of reviewer comments.

FIG. 1 illustrates a method for resolving inter-reviewer conflicts by generating a minimal question set for each of the reviewers that, upon receiving responses to the question set, will resolve the conflicts. At 101 the system receives a plurality of review comments from each of a plurality of reviewers who are tasked with reviewing a document. In other words, the system receives multiple review comments from each of the document reviewers. Receiving the review comments may include each of the reviewers or another user providing comments to a central system, uploading comments, or the like. Alternatively, receipt of the review comments may include a user providing a document that includes review comments to the system, for example, by uploading a reviewed/commented document, providing access to the reviewed/commented document, or the like.

At 102 the system may categorize each of the review comments for each of the reviewers. In other words, the system maintains identification of the reviewer who provided the comment and categorizes each of the comments provided by a single reviewer. The system performs the same categorization for each of the remaining reviewers. To categorize the comments the system may first categorize the comments into one of a plurality of review topics. The review topics may be dependent on the document type. For example, a document for a grant proposal may include a funding topic, whereas a document for a technical presentation may not include a funding topic. Alternatively, the topics may be provided by a user and the system may simply categorize each of the comments based upon the provided topics. Some possible high-level topics include novelty, related words, results, relevance, writing style, mathematical formulation, and the like. A user can also customize the topics based upon the setting of the document, for example, the user may choose different topics for documents being presented at a symposium versus a document being submitted to a journal. If a single comment includes different portions that appear to belong to different topics, the system may break up the comment into the different portions and categorize each of those portions. Alternatively, the system may simply duplicate the comment across the multiple topics so that the comment appears in all applicable topics.

The system may also perform a fine-tuned categorization where each of the comments provided within a single high-level categorization are further classified or categorized into more specific or detailed topics. For example, the system may further classify or categorize comments provided in the novelty topic into technical or non-technical novelty topics. In either the high-level categorization or the fine-tuned categorization the system may use a deep learning technique to classify phrases of the review comments into different topics. Thus, to perform the categorization the system may use natural language processing to identify words and phrases within the comments and also to identify syntactic and/or syntax roles of the words or phrases within the comments. The system can then use either deep learning techniques or dictionary based matching to classify the identified words or phrases into different topics.

At 103 the system determines whether there is a conflict between review comments of different reviewers. The conflict analysis is performed within the different topics. In other words, the system analyzes all the comments provided by different reviewers that have been categorized into a particular review topic. Within each of these topics, the system determines if there are any conflicts between the comments provided by different reviewers. To identify if any conflicts exist the system performs a sentiment analysis on each of the comments within the topic and categorizes the sentiment of the comment. For example, the system may categorize a comment as having a positive sentiment, a negative sentiment, a neutral sentiment, or the like. If the comment has multiple parts, each having a different sentiment, the system may break the comment into different portions and then sentimentally categorize each of the portions. Sentiment analysis may be performed using natural language processing techniques and/or a sentiment model that is unique to the topic. In other words, the sentiment model that determines the sentiment of the comment may be unique to each topic so that a more accurate sentiment conclusion can be determined.

Once the system has performed the sentiment analysis for each of the comments within the topic, the system compares the sentiment of comments within the topic provided by different reviewers. In other words, the system is trying to determine if different reviewers provided conflicting comments. Thus, the system compares the sentiment of comments within a topic provided by one reviewer against the sentiment of comments within the same topic provided by another reviewer. If the sentiment of the comments provided by reviewers is different, the system may determine that a conflict exists between the review comments provided by the different reviewers. For example, the system may identify a conflict if a review comment provided by one reviewer and categorized into one topic has a negative sentiment and a review comment provided by a different reviewer and categorized into the same topic has a neutral sentiment. As another example, the system may identify a conflict if a review comment provided by one reviewer and categorized into one topic has a positive sentiment and a review comment provided by a different reviewer and categorized into the same topic has a negative sentiment.

The system may also identify a conflict within a single comment provided by a reviewer. An example of such a conflict is when the comment is a subjective comment that includes no supporting detail for the comment. In other words, if a reviewer provides an overall general comment but does not provide any reasoning or details for the comment, the system can identify this comment as having a conflict even though it is not in direct conflict with a comment provided by another reviewer. In order to identify a comment that is subjective with little detail or reasoning, the system can generate a question from the comment. Generation of the question may be performed using deep learning methods or models. Once the question is generated, the system may analyze the comment to determine if the answer to the question appears in the comment. In other words, the system can treat the comment as a question-answer generation problem. If the answer does appear within the comment, the system can discard that question. If answers appear to all generated questions, then the system can categorize the comment as a proper subjective comment having details and/or reasoning. If the comment does not include answers to some of the questions, the system can mark the comment as non-explained and, therefore, as a comment having a conflict.

Another example of detection of a conflict which does not include a direct conflict with another reviewer's comment is a comment that requires extra validation. A comment that requires extra validation is a comment that indicates that something is missing, incorrect, or the like, and requires a person to verify or validate whether the information is actually missing or incorrect. These extra validation conflicts can be identified using a deep learning method or model or natural language processing technique to analyze the comment and identify that the comment can be categorized as a validation comment.

If the system determines that there is not a conflict at 103, the system may discard the review comment for question generation at 105. In other words, if the system determines that a review comment does not need additional input by a reviewer, the system will not use that comment for question generation.

If, on the other hand, the system determines there is a conflict at 103, the system will generate a question set based upon the conflict at 104. The system will generate a question set for each of the reviewers based upon conflicts identified that correspond to the reviewer. In other words, the system generates unique question sets for each of the reviewers. The unique question sets may contain some of the same questions across reviewers. However, a question set for one reviewer will not be identical to a question set for another reviewer. The system attempts to generate a minimal question set for each of the reviewers. A minimal question set is a question set that has the fewest number of questions that are necessary for resolving the identified conflicts. This helps to reduce the number of questions presented to the reviewers, thereby providing a more efficient system. The question sets includes questions where a response provided by the reviewer would resolve the identified conflict. In other words, the generated questions are those questions necessary for resolving the conflict.

Generation of the minimal question set is based upon the conflicts identified from the sentiment analysis, the subjective review analysis, and the extra validation analysis. In other words, the system generates questions that can resolve any of the conflicts identified from the sentiment analysis, subjective review analysis, and the extra validation analysis. To generate the questions the system uses a deep learning model that is trained for question generation based upon the identified conflicts. From the model the system can generate questions using a natural language processing technique so that the questions are provided in a manner understandable by the reviewer, specifically, a natural language question. Before presentation to the reviewers, the system may reduce the questions to a subset of minimal questions.

To produce the minimal questions the system may first validate the generated questions against identified parameters. These parameters may be based upon a submission setting for the document, for example, a symposium, a grant proposal, a presentation, a technical manual, or the like. Each of the submission settings may have different features or aspects that are expected within a submitted document. For example, one submission setting may require more technical details than another submission setting. Thus, based upon the submission setting, the system may determine that some of the questions are irrelevant. In other words, if a generated question would request additional details that are not necessary for the submission setting, the system may identify that question as irrelevant and discard that question. Another technique for reducing the number of questions may be to compare the questions against other generated questions to determine if the answer to one of the questions would also answer the other question. In this case, the system may identify one of the questions as redundant and discard that question. The system may also compare questions generated across reviewers to determine if some of those questions would be redundant and may then discard one of the redundant questions. In other words, if an answer provided by one reviewer would answer a question generated for another reviewer, the system may identify one of those questions as redundant and discard that question.

Thus, the described system and method provide an improvement over conventional system for document review by providing a system that can automatically generate minimal question sets for each of the reviewers such that responses to the question sets resolve any conflicts or subjective comments that were identified. Such a system provides a technique that is less time consuming, less labor intensive, and more efficient than conventional manual techniques that require many communications between reviewers and/or document drafters.
